Tris-(phenyl-phosphin-sulfid), also known as triphenylphosphine sulfide, is an organophosphorus compound with the chemical formula (C6H5)3PS. It is a colorless, crystalline solid that is soluble in organic solvents. Tris-(phenyl-phosphin-sulfid) is formed by the reaction of triphenylphosphine with sulfur, resulting in a molecule with a phosphorus-sulfur bond. Tris-(phenyl-phosphin-sulfid) is used as a ligand in coordination chemistry, particularly in the formation of metal complexes, and has applications in catalysis and the synthesis of various organic compounds. Its stability and reactivity make it a valuable intermediate in the preparation of other phosphorus-containing compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 1486-35-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,8 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1486-35:
(6*1)+(5*4)+(4*8)+(3*6)+(2*3)+(1*5)=87
87 % 10 = 7
So 1486-35-7 is a valid CAS Registry Number.

On Organophosphorus Compounds, XXII. 1,2-Diaryl-1,2-dibromodiphosphanes

Hinke, Axel,Kuchen, Wilhelm

, p. 3003 - 3010 (2007/10/02)

1,2-Diaryl-1,2-dibromodiphosphanes R(Br)P-P(Br)R 2 (R = C6H5; 4-XC6H4, X = CH3O, F, Cl) were prepared by dehalogenation of RPBr2 with magnesium in a one-batch procedure.While solid 2 presumably consists of only one diastereomer there exists an equilibrium between meso-2, rac-2 and their disproportionation products RPBr2 and (RP)5 in solutions of 2.The influence of temperature, R and solvent on this equilibrium was investigated. - The reaction products of the dissolved phenyl compound 2a correspond to a reaction of its disproportionation products PhPBr2 and (PhP)5, the former preferably reacting on nucleophilic substitution, the latter with electrophilic agents.Under heterogenous conditions diphosphanes Ph(R)P-P(R)Ph can be obtained from 2a and LiR.
